May fit other models too. The muffler is in place of the resonator. Simply cut the resonator and clamp on the custom Billy Boat exhaust. Has quad 3.5" tips. Just a feeler. I am gauging interest and researching the STS Turbo which will eliminate the Quads. Also will eliminate my Dual Duct intake along with my dual RPi scoops if that. Labor to create this amazing sounded Billy Boat Quad exhaust was a pretty penny. The exhaust alone cost $959 plus shipping. Black painted quad tips werre $150. Labor to weld and create this setup flawlessly is $400. I will let go of this exhaust for $1000 obo. Locals preferred. If ur far away and need shipping, you will have to pay shipping. I dont think there's a better sounding exhaust. No droning, decently loud on the outside and quiet on the inside.
Once again, gauging interests. I am preparing to spend about $8K for the STS turbo so I need to see if anyone wants the exhaust first. Also need to see who is skilled enough to install and tune the STS turbo first.

STS Turbo!! 
I cant wait to see it installed!!!
I am pretty sure there are some shops in NY that can install STS (see the website of STS they might have dealers in NY or NJ).
and don't forget the Quaife LSD. it is a must!
Good luck to sell the exhaust!

+1, john, get the M5, save turbo $8k, you only need $30k more, part out your car and trade for used M5, maybe 2006, you are not far away from M5 if you have $8k for turbo already

STS turbo would be 
Not sure on the reliability. Definitely be one of a kind. With all the mods and a STS installed. You can probably be featured in a magazine or something.
That's going to be one crazy ride.

thats exactly what I want. i dunno about reliability either. As for M5, I put too much time and $ into the car to sell it, part it out, and buy an M5 unless someone pays me $30K+
